Nuh's preaching to His People, and Their Response

Here Allah tells us about His servant and Messenger Nuh, peace be upon him, who was the first Messenger sent by Allah to the people of earth after they started to worship idols. Allah sent him to forbid that and to warn people of the consequences of idol worship. But his people belied him and continued their evil practice of worshipping idols besides Allah. Allah revealed that their disbelieving in him was akin to disbelieving in all the Messengers, So Allah said:

كَذَّبَتْ قَوْمُ نُوحٍ الْمُرْسَلِينَ - إِذْ قَالَ لَهُمْ أَخُوهُمْ نُوحٌ أَلاَ تَتَّقُونَ

يَوْمَ لَا يَنفَعُ مَالٌ وَلَا بَنُونَ ﴿88﴾ إِلَّا مَنْ أَتَى اللَّـهَ بِقَلْبٍ سَلِيمٍ ﴿89﴾

The Day when neither wealth will be of any use (to any one) nor sons, [ 88] except to one who will come to Allah with a sound heart, [ 26:89]
